Lol, the world's leading scientists are in Europe. People emigrate to Switzerland and surrounding nations, such as Germany, because the capacity to genuinely research is unparalleled in more 'capitalist' nations as grants in Europe are given more leniently for genuine sake of discovery, not just for profit. The vaccines for Covid that are being used outside of China, were made in Belgium for one brand and UK for the other. The most ambitious and groundbreaking research is consistently and has been consistently done in Europe.
I looked at your link... It ranks based on papers published and ignores country size entirely yet still European nations dominate the top ten... The top 2 are massive compared to the nations following them.
China doesn't share its research with the world, it may as well be non-scientific since it only reveals 5% of its research at most for the benefit of international science.
